There is a heckuva lot more to life than just Baseball.
I'm a big believer in "do what you love". Find something that you love doing and work your tail off becoming great at it. Former college athletes certainly gave an advantage over many in our society, in terms of already having honed a tremendous work ethic.
It can be a transition that could potentially take awhile to finding something new that you love, I don't want to minimize that.
For those that are Baseball lifers, once the playing days are done it is time to get into coaching or scouting.
